Kevin Doyle and Wayne Hennessey are among three Wolves players hoping to be fit for the weekend after being ruled out of international duty.
Hennessey and Dave Edwards have picked up knocks preventing them from representing Wales in the Gary Speed Memorial match against Costa Rica on Wednesday evening.
The Wales goalkeeper's ankle was damaged in a late challenge from Shola Ameobi during the closing stages of Saturday's draw at Newcastle.
Doyle will miss the Republic of Ireland's home friendly with the Czech Republic as he is suffering from a tight hamstring.
The trio will be monitored with the aim of being available for Sunday's trip to Fulham and Steve Kemp, head of Wolves' medical department, is remaining optimistic.
Kemp said: "Having spoken to the medical teams from the two countries, they kindly agreed to allow the players to come back for assessment once it was clear they would not be involved tonight (Wednesday).
"We will now be able to treat them here at Compton and hopefully ensure they are available for Sunday's game with Fulham."
Both Hennessey and Edwards, who has a slight knee injury, will still attend the game at the Cardiff City Stadium in honour of the former Wales manager Speed, who died in November.
